Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-66449 exists.\n\nAffected product: C4illin ConvertX. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-66449/ (Markdown: https://insights.sbomify.com/CVE-2025-66449/index.md)","id":"CVE-2025-66449","markdown":"https://insights.sbomify.com/CVE-2025-66449/index.md","name":"CVE-2025-66449","record":{"aliases":["GHSA-cpww-gwgc-p72r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ConvertX file converter","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit path traversal in ConvertX to write arbitrary files, overwriting binaries to achieve remote code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"convertx","vendor":"c4illin"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"ConvertXis a self-hosted online file converter. In versions prior to 0.16.0, the endpoint `/upload` allows an authenticated user to write arbitrary files on the system, overwriting binaries and allowing code execution. The upload function takes `file.name` directly from user supplied data without doing any sanitization on the name thus allowing for arbitrary file write. This can be used to overwrite system binaries with ones provided from an attacker allowing full code execution. Version 0.16.0 contains a patch for the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"ConvertX has Path Traversal that leads to Arbitrary File Write and Arbitrary Code Execution","id":"CVE-2025-66449","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"LibreChat JSON Injection in Chat POST Allows Remote Resource Inclusion and PXSS via Image Upload","id":"CVE-2025-66450"},"packages":[],"prev":{"headline":"vLLM vulnerable to remote code execution via transformers_utils/get_config","id":"CVE-2025-66448"},"products":["ConvertX"],"published":"2025-12-16","related":[{"cvss_score":8.1,"headline":"ConvertX Vulnerable to Arbitrary File Deletion via Path Traversal in `POST /delete`","id":"CVE-2026-24741","kev_date_added":null,"published":"2026-01-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-12-16","vendors":["C4illin"]},"summary":"Authenticated attackers can exploit path traversal in ConvertX to write arbitrary files, overwriting binaries to achieve remote code execution.","url":"https://insights.sbomify.com/CVE-2025-66449/"}
